# Installation

```{important}
If you are converting an existing game from a previous Evennia version, [see here](./Installation-Upgrade.md).
```

The fastest way to install Evennia is to use the `pip` installer that comes with Python (read on).
You can also  [clone Evennia from github](./Installation-Git.md)  or use [docker](./Installation-Docker.md).  Some users have also experimented with [installing Evennia on Android](./Installation-Android.md).

## Requirements

```{sidebar} Develop in isolation
Installing Evennia doesn't make anything visible online. Apart from installation and updating, you can develop your game without any internet connection if you want to.
```
- Evennia requires [Python](https://www.python.org/downloads/) 3.10 or 3.11 (recommended). Any OS that supports Python should work.
	- _Windows_: In the installer, make sure you select `add python to path`.  If you have multiple versions of Python installed, use `py` command instead of `python` to have Windows automatically use the latest.
	- _Windows:_ If you want to use Python 3.11, you must also install the [Windows SDK](https://aka.ms/vs/16/release/vs_buildtools.exe). Run the linked installer. Click the `Individual Components` tab at the top, then search and checkbox the latest `Windows 10 SDK` (also for older/newer Windows versions). Then click `Install`. If you have trouble, use Python 3.10 for now (2022).
- Don't install Evennia as administrator or superuser. 
- If you run into trouble, see [installation troubleshooting](./Installation-Troubleshooting.md).

## Install with `pip`

```{important}
Using a light-weight [Python virtual environment](./Installation-Git.md#virtualenv) is optional, but _highly recommended_ in order to keep your Evennia installation independent from the system libraries. The virtualenv system is a part of Python and will make your life easier!
```

Evennia  is managed from the terminal (console/Command Prompt on Windows). Once you have Python, you - after activating your virtualenv if you are using one - install Evennia with

    pip install evennia

Optional: If you use a [contrib](../Contribs/Contribs-Overview.md) that warns you that it needs additional packages, you can  install all extra dependencies with 

	pip install evennia[extra]

To update Evennia later, do 

    pip install --upgrade evennia

```{note} **Windows users only -** 
You now need to run `python -m evennia` once. This should permanently make the `evennia` command available in your environment.
```

Once installed, make sure the `evennia` command works.  Use `evennia -h` for usage help. If you are using a  virtualenv, make sure it's active whenever you need to use the `evennia` command later.

## Initialize a new game

We will create a new "game dir" for you do create your game in. Here (and in
the rest of the Evennia documentation) we refer to this game dir as  `mygame`, but you should of course name your game whatever you like.

```{sidebar} Game-dir vs game-name
The game-dir you create doesn't have to match the name of your game. You can set the name of your game later by editing `mygame/server/conf/settings.py`.
```

    evennia --init mygame

This will create a new folder `mygame` (or whatever you chose) in your current location. This
contains empty templates and all the default settings needed to start the server.

## Start the new game

    cd mygame 
    evennia migrate

This will create the default database (Sqlite3). The database file ends up as `mygame/server/evennia.db3`. If you ever want to start from a fresh database, just delete this file and re-run `evennia migrate` again.

    evennia start

Set your user-name and password when prompted. This will be the "god user" or "super user" in-game.  The email is optional.

> You can also [automate](./Installation-Non-Interactive.md) the creation of the super user.

If all went well, the server is now up and running. Point a legacy MUD/telnet client to `localhost:4000` or a web browser at [http://localhost:4001](http://localhost:4001) to play your new (if empty) game! 

Log in as a new account or use the superuser you just created.


## Restarting and stopping


You can restart the server without disconnecting players:

    evennia restart

To do a full stop and restart (will disconnect players):

    evennia reboot

Full stop of the server (use `evennia start` to restart):

    evennia stop

See [Server start-stop-reload](./Running-Evennia.md) page for more details.

## See server logs

Log files are in `mygame/server/logs`. You can tail them live with

    evennia --log

or

    evennia -l

Stop viewing the log by pressing `Ctrl-C` (`Cmd-C` for Mac). 

You can start viewing the log immediately by adding `-l/--log` to `evennia` commands, such as

    evennia start -l

## Server configuration 

The server configuration file is `mygame/server/settings.py`. It's empty by default. Copy and change  only the settings you want from the [default settings file](./Settings-Default.md). See the [Settings](./Settings.md) documentation for more info.
 
## Register with the Evennia Game Index (optional)

You can let the world know that you are working on a new Evennia-based game by 
registering your server with the _Evennia game index_. 

    evennia connections 

Just follow the prompts. You don't have to be  open for players to do this - you just mark your game as closed and "pre-alpha".

See [here](./Evennia-Game-Index.md) for more instructions and please [check out the index](http:games.evennia.com)  beforehand to make sure you don't pick a game name that is already taken - be nice!
